The 1906-O Barber half dollar was struck in 90% fine silver at the New Orleans Mint. This attractive silver coin is a prized keepsake from the first decade of the 20th century. At the time, America was changing from an agrarian economy to an industrial society, but there were some growing pains. In 1906, Standard Oil was accused by the Interstate Commerce Commission of being a monopoly, and the Pure Food and Drug Act had to be enacted to protect the public from unsafe products.
